OpenAI Fires an Employee For Prediction Market Insider Trading (wired.com) 16

An anonymous reader quotes a report from Wired: OpenAI has fired an employee following an investigation into their activity on prediction market platforms including Polymarket, WIRED has learned. OpenAI CEO of Applications, Fidji Simo, disclosed the termination in an internal message to employees earlier this year. The employee, she said, "used confidential OpenAI information in connection with external prediction markets (e.g. Polymarket)." "Our policies prohibit employees from using confidential OpenAI information for personal gain, including in prediction markets," says spokesperson Kayla Wood. OpenAI has not revealed the name of the employee or the specifics of their trades.

Evidence suggests that this was not an isolated event. Polymarket runs on the Polygon blockchain network, so its trading ledger is pseudonymous but traceable. According to an analysis by the financial data platform Unusual Whales, there have been clusters of activities, which the service flagged as suspicious, around OpenAI-themed events since March 2023. Unusual Whales flagged 77 positions in 60 wallet addresses as suspected insider trades, looking at the age of the account, trading history, and significance of investment, among other factors. Suspicious trades hinged on the release dates of products like Sora, GPT-5, and the ChatGPT Browser, as well as CEO Sam Altman's employment status. In November 2023, two days after Altman was dramatically ousted from the company, a new wallet placed a significant bet that he would return, netting over $16,000 in profits. The account never placed another bet.

The behavior fits into patterns typical of insider trades. "The tell is the clustering. In the 40 hours before OpenAI launched its browser, 13 brand-new wallets with zero trading history appeared on the site for the first time to collectively bet $309,486 on the right outcome," says Unusual Whales CEO Matt Saincome. "When you see that many fresh wallets making the same bet at the same time, it raises a real question about whether the secret is getting out." [...] Though this is the first confirmed case of a large technology company firing an employee over trades in prediction markets, it's almost certainly not the last. Opportunities for tech sector employees to make trades on markets abound. "The data tells me this is happening all over the place," Saincome says.

  • Surely that's what these markets are built for primarily. It's gambling but less regulated so it's rife for it. The only thing I can't understand is why people bet against such random things, especially when there's such large money betting the other way.
  • Within hours of Altman telling Anthropic to stand strong against Trump and seeing claude get kicked out of their federal contracts, OpenAI announces it has a new Pentagon deal in the works.

    Lots of the slashdot usual suspects in the previous story fantasized about all the AI companies refusing to service the US government. How funny the opposite was happening (per usual).

    • It's not funny, it's obvious. OpenAI has a deep profitability hole to fill. The taxpayers, aka tariff payers, aka American citizens have the money to fill that hole.
  • No way this guy doesn't have a job in the current U.S. Administration, maybe even the Cabinet, by next week. /s

  • Maybe he should've asked ChatGPT how to set up bets to not be so obvious.

    Seriously, opening 13 new wallets and immediately placing one massive winning bet on each is asking to be investigated.

    "Corrupt employee of corrupt company led by corrupt CEO uses platform of corrupt company led by corrupt CEO to engage in the corruption the platform was expressly designed, built, and run to encourage and reward."
  • Bright, risk your 6-7 figure job with 5-6 figure bonus and 6-8 figure stock options for $16k. Additionally to do so with zero thought regarding disguising the bet and accounts. They probably also registered with an OpenAI.com email address!

  • ... that if you choose to play "prediction markets" that you deserve to lose your money.
  • So, there's an artificial constraint that prevents me from profiting from the information that happens to be in my head, the information that I helped to contribute to with my own hard work?

    But I can use all that information to help the shareholders profit, including the CEO, and the board of directors who themselves probable put this rule into place.

    So, it's work really hard for me but stay poor so I can control you.

Cobol programmers are down in the dumps.
